I've recently noticed after finally playing something int he DVD-rom on my PC, that the sound output is very low, so low that I have to turn my speakers up all the way and the Windows sound settings all the way just to be able to hear it decently, it also plays sme mpeg files very low as well, I've tried about 6 DVD's and all the same problem,I've used PowerDVD, Nero ShowTime, VideoLan, Media Player classic, all the same problem, I am using an onboard Realtek sound chipset (Not sure what model, will look it up if needed.) and I am running all the proper codecs (K-Lite full codec pack.) - everything else seems to play fine, jsut not DVD's and some mpegs.

Is it a laptop your talking about. if it is, try hooking up external speakers to see if the sound problem still persists

And if your using external speakers, are you sure its not the speakers that are having the problem. try using headphones or other speakers to test it

No, its a desktop PC, I've tried it with 2 sets of desktop speakers (Both of which I know work) and with 2 pairs of headphones, same things happen.

If you've already tried to get the latest drivers for your card i would be guessing its a hardware related issue. I'm guessing by your stats that the computer is fairly new. If you have any old systems or sound cards i would try those out and see if the problem persists or reseat the card in another slot in the computer. Hope this helps

I'm not a hardware expert, but something like this has happened with my old Nvidia TNT2 card before. No display, so i removed it reseated it and it seemed to work fine after that.
